Error collecting sales in auction after 2-12-18 update

[Futumsh]

It looks like with the new client, when you complete / cancel an auction, it does complete or cancel it properly, and you get the gold or item, but the ui doesn't update properly and shows the combined list from before and after the action. This will be fixed for the next client, but noone should lose anything from this.

There was a way to fix this without a new client, so this should be fixed in a patch shortly.
